Pictures: 33-year-old star joins rest of Arsenal squad in training ahead of Wednesday’s Chelsea clash

Arsene Wenger’s men are gearing up for what could be a decisive clash against Chelsea in the Premier League on Wednesday.

The Gunners are struggling to compete with the rest of the so-called big six this season as they remain sixth in the table.

Despite managing to beat Crystal Palace last Thursday, it was back to square one for Arsenal on Sunday as they were held to a 1-1 draw by West Brom.

With the Gunners hit by several injuries, this could be an opportunity for Per Mertesacker to return to into the starting eleven.

The 33-year-old came on to replace Laurent Koscielny during the second half of Sunday’s draw at the Hawthorns.

Here were a few pictures as the German veteran joined the rest of the Arsenal first team in training on Monday.
